Always wrap text codes in quotation marks (e.g., "Top" ) within the Properties panel. Omitting quotes causes validation errors.

Subassembly Composer (SAC) for AutoCAD Civil 3D is a game-changer for infrastructure designers. It allows you to build complex, custom road cross-sections that the standard tool palettes just can't handle—all without needing to learn programming.

Note: For detailed, step-by-step PDF tutorials, it is recommended to search for "FDOT Civil 3D Subassembly Composer Manual PDF" for comprehensive documentation.

Define the (e.g., LaneWidth , PavementThickness ). Space characters are not permitted in parameter names.

Auxiliary Points and Auxiliary Links serve as internal construction lines. They are visible in the Subassembly Composer preview for calculation purposes but do not render or build geometry inside the final Civil 3D corridor. They are ideal for calculating intersection points or temporary slopes.

While video tutorials are helpful, keeping a handy is the best way to reference syntax and node logic while you work. Download the official guides, start with a simple shape, and you’ll be creating complex custom corridors in no time.
